Hi! Is there any significant difference in power/economy between low and higher octane fuels with the 3.0 engine? Thanks.

Nah. It won't make use of the higher octane fuel, the only difference will be on your wallet...
I do personally think there is a difference between branded (Eg Shell) fuel than supermarket ones.. so I'd be tempted to recommend a branded 95 Ron...

You will get slightly better mpg (driven the same way), and slightly more sprightly if driven harder.
Worth the extra? Probably not.

There is a difference.
super gives a clener burn,the car will be a lot smoother on acceleration,and a better delivery and if used in a 3.2 may delay the onset of the pre-cat codes.
As a by some VALUE fuels(every little). contain more ethonal and other cheap additives,but it still meets its BS standard just, hence use a good branded fuel,as for extra miles,about 15 -20 more miles extra,with super fuels,.

Many of the high octane fuels contain a lot more Ethanol too, though, as it's a cheap/easy way to increase octane rating!
TBH, you need to put the marketing bowlocks aside and try it yourself, ideally using blind testing. Get someone else to fill your car up a couple of times without you knowing what they've put in, and see if you can tell. ;)
It does make a big difference to turbocharged or very highly strung cars, as they tend to back off quite a lot if they detect any knock, so ignore any testimonials from scooby / skyline drivers, etc. The Omega isn't such a car, however, and I've never seen any level of knock retard on 95 unleaded. As such, I very much doubt there's a worthwhile benefit.
